我正在尝试通过使用Expo来学习React Native（一般来说，我是相当陌生的编程人员）。我遵循了我可以从Expo文档和有用的视频中找到的所有设置说明，但是我仍然遇到以下错误。我已经使用Nodejs v12.13和v13进行了尝试（因为有警告，尽管它是当前版本，但它不支持v13）。我尝试搜索，发现了类似的问题，但是没有一种解决方案对我有用。我觉得我在某个地方遗漏了一个简单，关键的错误，希望得到一些帮助！
我在Windows 10上|世博会v3.4.1 | Nodejs v12.13（尽管尝试使用当前版本v13会产生相同的错误） npm v6.12
我按照世博会网站上的步骤开始：
安装NodeJS
在CMD中（以管理员身份运行），安装Expo npm install expo-cli --global
expo init rn-first-app cd rn-first-app npm start Expo按预期在浏览器中打开一个页面，并且在崩溃/退出之前始终持续约1-3秒，并且我收到以下错误消息：
c:\Users\Michael\Documents\rn-first-app>npm start
